Highlights

• Division 296 is expected to become an important consideration in annual superannuation planning for individuals with balances approaching or exceeding AUD 3 million.
• The proposal does not change existing contribution caps, but it may influence how high-balance investors think about future contributions and retirement strategies.
• End-of-financial-year reviews, balance monitoring, liquidity planning, and accurate valuations could become increasingly important under the proposed framework.
• Key uncertainties remain around the treatment of unrealised gains, threshold indexation, commencement timing, and the final legislative design.

Each year, Australians revisit their superannuation as part of a familiar rhythm: reviewing contributions, checking caps, and tidying affairs before the end of the financial year. In 2026, that annual cycle carries an extra consideration. The proposed Division 296 measure, often described as the $3 million super tax, adds a new factor for those with large balances, and shapes how the year's planning conversations are likely to unfold.

This article takes a forward-looking, strategy-oriented view of 2026. It sets the measure within the ordinary planning calendar, considers how it interacts with contribution caps and end-of-financial-year decisions, and outlines what to keep an eye on as the year progresses. It is general information, not advice, and it avoids alarm in favour of practical perspective.

Direct answer: a quick summary

Division 296 is a proposed Australian measure applying an additional 15 per cent tax on earnings attributable to the portion of an individual's total superannuation balance above $3 million, assessed per person across all funds at year-end. The original design measured earnings via the change in balance, potentially including unrealised gains, with the threshold un-indexed. For 2026 planning, the practical approach is to fold the proposal into the normal cycle while confirming final detail against the legislation.

Why this matters now

Superannuation strategy works best when it is steady and forward-looking rather than reactive. In 2026, the proposal sits alongside the usual settings savers consider each year, so weaving it into the existing cycle is more efficient than treating it as a separate emergency. For those near or above $3 million, the year is an opportunity to align contributions, balances and records with a clearer understanding of the measure.

Timing reinforces the point. The proposal has progressed enough to warrant attention but is still subject to final design and start date. That makes 2026 a year for preparation and information-gathering, where decisions can be staged and revisited rather than rushed.

There is also the natural cadence of the financial year. Contribution decisions, cap usage and end-of-year reviews all cluster at predictable points, and these are precisely the moments when the measure is most relevant to a high-balance saver's choices.

Who may be affected

The measure targets individuals with a total superannuation balance above $3 million, tested across all funds at year-end. The test is individual, so it is assessed per person, not per household, and partners can have very different positions.

Typical profiles include long-term savers, business owners who contributed large sums, and members whose assets have grown strongly. Initially a small share of account holders, in the tens of thousands, are affected, though the un-indexed threshold in the original design means the group could widen over the years.

For 2026 planning, the more useful question is dynamic: are you above the threshold, just under it, or moving toward it through contributions and growth? Those near the line have the most to consider as they plan the year's contributions.

What investors should understand

The additional tax is proportional, applying only to earnings attributable to the part of a balance above $3 million. The proportion is the amount above the threshold divided by the total balance, so exposure rises with the size of the balance above the line.

The most debated feature of the original proposal is how earnings are measured. By looking at the year-on-year change in balance, adjusted for contributions and withdrawals, the original design could include unrealised gains. This affects how a strong investment year might translate into a liability, and should be treated as an original-proposal feature subject to final legislation.

Liability rests with the individual, who can generally elect to pay personally or from super. Within an annual strategy, that election interacts with cash flow and with how much capital remains inside super to keep compounding.

Contribution caps and the 2026 planning cycle

Contributions are the heart of most annual super strategies, and they take on added nuance for high-balance savers. Concessional and non-concessional contribution caps continue to govern how much can be added each year, and existing rules already restrict some contributions once a balance is large. For those near $3 million, the question is less about maximising contributions and more about whether additional contributions still suit the overall plan.

The measure does not change the caps themselves, but it reframes the decision to use them. Adding to a balance that is already above the threshold increases the base on which the proportional calculation applies. This does not make contributions inadvisable, but it does mean their role deserves fresh thought within the year's strategy.

For savers still well below $3 million, the ordinary logic of building super through the caps may be largely unchanged. The 2026 conversation simply adds a longer-term awareness of the threshold to the usual cap planning, particularly for younger high earners on a steep trajectory.

End-of-financial-year considerations

The end of the financial year is when many super decisions are finalised, and the measure adds a few points to the usual checklist. Because the threshold is tested on the year-end balance, the figures struck at that point matter, which makes accurate records and valuations especially valuable as the year closes.

EOFY is also when savers review whether they have used available caps, whether any catch-up provisions apply, and how their balance has moved over the year. For high-balance members, layering an awareness of Division 296 onto these familiar tasks helps ensure the year's choices fit a longer-term view rather than just the immediate tax year.

SMSF and managed super fund considerations

Self-managed superannuation fund (SMSF) trustees carry direct responsibility for valuations, records and meeting any liability, and often hold illiquid assets. For these members, the 2026 cycle should include disciplined year-end valuations and attention to liquidity, since an earnings figure that includes unrealised gains could create a liability without matching cash.

Members of large APRA-regulated funds have much of the reporting and calculation handled for them, with figures aggregated by the relevant authorities. Their 2026 focus tends to be on understanding the numbers provided and how any liability would be funded.

For anyone with balances across both fund types, the individual-level aggregation is the anchor: balances combine across all funds to test the threshold, so the annual review needs a consolidated view.

Possible planning options to discuss with an adviser

These are areas commentators discuss generally. They are not recommendations and depend on individual circumstances. Explore them with a licensed adviser and tax specialist.

• Reviewing the size and timing of voluntary contributions within the year's cap planning.
• Considering partial withdrawal and recontribution strategies where eligible.
• Assessing whether some assets sit better outside super, such as in trusts or investment bonds.
• Planning liquidity so any future liability can be met without forced sales.
• Considering philanthropic structures for those with charitable goals.

Risks and uncertainties

The key uncertainty for 2026 strategy is that the proposal is not final. Design and timing have shifted in debate, and the unrealised-gains methodology and lack of indexation remain contested. Building the year's plan around a feature that may change calls for flexibility rather than firm commitment.

Restructuring during the year can crystallise capital gains tax, duties and compliance costs, and may not align with the final rules. Annual strategy should therefore keep options open and avoid irreversible moves while detail is settling.

Perspective also matters: super remains concessionally taxed under the proposal and continues to play a central role in most retirement strategies. The aim in 2026 is to refine, not abandon, a long-term plan.

What to watch before 1 July 2026

The source frames a potential start around 1 July 2026, treated here as indicative and subject to legislation. Signposts to watch through the year include:

• Whether the final earnings methodology retains any treatment of unrealised gains.
• Whether the $3 million threshold is indexed in any final form.
• The confirmed start date and any transitional arrangements.
• Any interaction with contribution caps or existing balance-based rules.
• Guidance on valuation and reporting for the year-end calculation.
